bearcat Posted January 21, 2019 Share #2 Posted January 21, 2019 You can not "jump" from 5.2 to 6.x using the control panel, you will need to read and follow this (or this) guide. Quote Link to comment Share on other sites More sharing options...

bearcat Posted January 22, 2019 Share #4 Posted January 22, 2019 @levikats11 If you try to ckeck your networks settings, they will appear blank I guess From earlier experience with a problem like that, after upgrading (from a different bootloader) try these steps: Activate the SSH service in DSM (if not active) Connect to your NAS with an SSH client (e.g. putty) (or from Win 10, open a cmd window, run : ssh admin@my.nas.ip (replace with the actual IP) Enter your credentials (user: admin) Change folder to root (cd /) Delete the xpenoboot folder (sudo rm -r .xpenoboot) If the SSH service keeps stopping, you have to be quick You might have to reboot after this.
